Information technology — JPSearch — Part 3: Query format
ISO/IEC 24800-3:2010, also known as “JPSearch Query Format (JPQF)”, provides a standardized interface for image search and retrieval systems in three aspects - input query format, output result format and query management - as a specialization of ISO/IEC 15938-12:2008 for images and accompanying metadata. The top-level tools defined in ISO/IEC 24800-3:2010 are InputQuery, FetchResult, OutputResult and Management. Both InputQuery and FetchResult tools belong to input query format. The input query format provides users/systems with a set of precise input parameters to describe their search criteria in addition to a set of preferred output parameters to depict the return result sets through InputQuery. Through InputQuery, users can use queries of various types, such as query by media, query by description, query by free text, and combine them using algebraic or logical expressions. Through FetchResult, users can retrieve search results of a query from the past. When a query request is issued using the asynchronous mode, the FetchResult element is used to indicate the preparedness of the user to receive results. When a query request is issued using the synchronous mode, the FetchResult element is used to receive individual pages of the result set (if paging is activated). The OutputResult, which is the output result format, provides users/systems with a set of output parameters to describe the aggregated return result sets for user presentation or machine consumption. The Management tool, which is the query management tool set, provides a means for selecting services (e.g. MPEG-7 database or Core Metadata services) or aggregated services (e.g. service provider that administers a set of different services) based on service properties (e.g. supported query format, supported metadata standard). The goal is to define a query language that provides the industry with a standardized format to accept and respond to user/system specification for image searches. In the framework of JPSearch, the JPSearch Query Format is designed to be used as an interface between querying client and answering servers, as well as between aggregation service agent and individual service providers.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 24800-3 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.
ISO/IEC 24800 consists of the following parts, under the general title Information technology — JPSearch:
⎯ Part 1: System framework and components
⎯ Part 2: Registration, identification and management of schema and ontology
⎯ Part 3: Query format
⎯ Part 4: File format for metadata embedded in image data (JPEG and JPEG 2000)
The following part is under preparation:
⎯ Part 5: Data interchange format between image repositories
Reference software will form the subject of a future Part 6.

Introduction
ISO/IEC 24800 aims to provide a standard for interoperability for still image search and retrieval systems.
There are many systems which provide image search and retrieval functionality on computer desktops, on the
World Wide Web (i.e., websearch), on imaging devices, and in other consumer and professional applications.
Existing systems are implemented in a way that tightly couples many components of the search process.
ISO/IEC 24800 provides an abstract framework search architecture that decouples the components of image
search and provides a standard interface between these components.
Aligning image search system design to this standard framework facilitates the use and reuse of metadata;
the use and reuse of profiles and ontologies to provide a common context for searching; and the provision of a
common query language to easily search across multiple repositories with the same search semantics. It
allows image repositories to be independent of particular system implementations; and allows users to easily
move or upgrade their image management applications or to move to a different device or upgrade to a new
computer.
This part of ISO/IEC 24800 contains the tools of the JPEG Query Format (JPQF) as an adaptation for the still
images domain of ISO/IEC 15938-12:2008. It addresses the normative aspects of the Query Format and also
illustrates some non-normative examples.
